qt-ble: add BLE packet debugging code
This is perhaps overly verbose, but the timing details helped figure out some EON Core download issues, and it's nice to see when things actually happen. It's also good to see when the data actually enters our queues, and when we read and write the packets. That might help debug the issues Fabio is seeing with the Mares Bluelink.
